1. In the Gram Stain procedure, which component acts as the mordant?

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.

2. A patient has suddenly developed shortness of breath and appears to be in significant respiratory distress. After calling the physician and placing the patient on oxygen, which of these actions is the best for the nurse to take when further assessing the patient?

Correct answer: B

Rationale: In a situation where a patient is in significant respiratory distress, bilaterally percussing the thorax to note any differences in percussion tones is a crucial nursing intervention. Percussion provides instant feedback regarding changes in underlying tissue density, which can give important clues about the patient's physical status. This hands-on assessment technique is readily available and can be performed promptly. Counting the patient's respirations, while important, may not provide as much detailed information as percussion. Ordering a chest x-ray and waiting for the results can cause a delay in assessing and addressing the patient's immediate needs. Inspecting the thorax for new masses and bleeding, although relevant, may not offer as much real-time information about the patient's condition compared to percussion.

3. A patient works with a nurse to establish outcomes. The nurse believes that one outcome suggested by the patient is not in the patient's best interest. What is the nurse's best action?

Correct answer: C

Rationale: In this scenario, the nurse should collaborate with the patient rather than impose personal opinions. While the nurse should respect the patient's autonomy, they also have a duty to provide guidance. By exploring possible consequences of the suggested outcome with the patient, the nurse can facilitate a discussion that helps the patient make an informed decision. This approach respects the patient's input while ensuring their well-being. Remaining silent (Choice A) may not address the issue, educating the patient unilaterally (Choice B) may be perceived as dismissive, and formulating an outcome without patient input (Choice D) disregards the patient's autonomy and preferences.

4. Match the abbreviation with the correct definition:

Correct answer: C

Rationale: The abbreviation 'ac' stands for 'ante cibum,' which means 'before meals.' 'Bid' means twice a day. 'Tid' means three times a day, and 'pc' means after meals. When interpreting medical abbreviations, it is crucial to understand their precise meanings to ensure accurate communication and patient care.

5. During a class on religion and spirituality, the nurse is asked to define spirituality. Which statement by the nurse best describes spirituality?

Correct answer: D

Rationale: Spirituality is a broad term that focuses on a connection with something greater than oneself and a belief in transcendence. It is a personal journey that arises from unique life experiences and the individual's quest to find purpose and meaning in life. The correct answer emphasizes the essence of spirituality, which involves seeking a connection with a higher power and believing in transcendence. Choices A, B, and C, on the other hand, define aspects of religion rather than spirituality. Choice A refers to a personal search for a supreme being, which is more aligned with religious beliefs. Choice B describes an organized system of beliefs about the universe, typically associated with religion. Choice C pertains to beliefs about existence after death, such as reincarnation or the afterlife, which are often religious concepts. Therefore, the best description of spirituality is focusing on a connection with something beyond oneself and a belief in transcendence.
